The short version

Keith Castaldi is listed as an executive officer and director on 11 SEC Form D filings by 4 issuers between Aug 2016 and Dec 2023: Fastener Holdco, LLC (Omaha, NE — manufacturing — 2016–2018; $186M reported sold to 100 investors), Heights Management Holdco, LLC (New York, NY — industry reported as "Other" — 2022–2023; $146.3M reported sold to 157 investors), IFS Management Holdco, LLC (Bell, CA — industry reported as "Other" — 2019–2022; $37.5M reported sold to 42 investors) and BradyIFS Management Holdco, LLC (Las Vegas, NV — industry reported as "Other" — 2023; $28.1M reported sold to 162 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as executive officer and director, over about 7 years. Across those companies the filings report $398M sold in total.

Listed alongside William Woo (8 shared filings), Howard A. Matlin (7 shared filings), Alec J. Hufnagel (5 shared filings), Stanley de J. Osborne (4 shared filings), James E. Whitley (3 shared filings) and 13 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Keith. Each name links to their own page.

All 4 issuers belong to the sponsor group Kelso (71 issuers, $10.1B reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Kelso has 71 companies on file and $10.1B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 5 court cases matching the name, 8 bankruptcy cases matching the name listed in Key records below.

What this means 13 records came back, including 1 court case still open — open cases can take years and cost money. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared 11 public filings for Keith Castaldi and found 8 differences, 3 worth asking the sponsor about: Keith Castaldi is no longer listed on the Aug 26, 2026 amendment; Keith Castaldi is no longer listed on the Dec 26, 2024 amendment; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

8 differences found between the filings for Keith Castaldi — 3 worth asking about (compared 11 filings on Oct 24, 2026)

Worth asking · Aug 26, 2022 – Aug 26, 2026

Keith Castaldi is no longer listed on the Aug 26, 2026 amendment — Heights Management Holdco, LLC

Keith Castaldi appears on the Aug 26, 2022 Form D (executive officer) but not on the Aug 26, 2026 Form D/A for the same offering.

What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.

Note · Nov 29, 2023 – Dec 26, 2023

Form D filed 27 days after the first sale — BradyIFS Management Holdco, LLC

The filing says the first sale was Nov 29, 2023. The Form D was filed Dec 26, 2023 — 27 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 12 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Form D · Dec 26, 2023 ↗BradyIFS Management Holdco, LLC — PartnerFacts page ↗
Sources
Note · Nov 22, 2019 – Dec 2, 2022

No amendment in the last 12 months on an offering that may still be open — IFS Management Holdco, LLC (latest filing Dec 2, 2022)

The latest filing for this offering is dated Dec 2, 2022 (first sale Nov 22, 2019). It reports $37,544,270 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

The latest filing for this offering is dated Aug 3, 2018 (first sale Jul 26, 2016). It reports $186,023,792 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Keith Castaldi is written 2 different ways on the filings

listed as "Keith Castaldi" on 8 filings (from Aug 3, 2016), and "Keith 10022 Castaldi" on 3 filings (from Dec 3, 2019).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Keith Castaldi is listed with 2 different address states: NY, NV

NY on 10 filings (Aug 3, 2016 to Aug 28, 2023); NV on 1 filing (Dec 26, 2023).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.
